Josnrnr. sTABELL, OE BUFFALO, NEW YORK.

To all who/n t may concern:

Be it known that I, Josnrii F. STABELL, a citizen of the United States, residing at Buffalo, in the county OfvErie and State of New York, have invented a new and useful mprovement in Apparatus for Use in Road- Bed Construction, of which the following is a specification.

Thisinvention relates more particularlyl to portable apparatus adapted for use in road constructionwork.

One object of the invention vide aiturntable adapted to be associated with a concrete mixer or other road material handlingm'achine, so that a truck or vehicle loaded with the material for the mixer or other Vmachine can be driven forwardly onto the turntable and turned about by rotating the turntable so 'that the material can be dumpedJdirectlyfrom the .rear of the vehicleinto .the mixer or other machine, thereby. making it unnecessary to carry the material in small quantities from a distance to the mixer, and thus savingla great deal of laborotherwise required in handling the material.

Another object is to mount the turntable on a wheeled carriage adapted to be supported by and to travel on the temporary parallel curbs or forms which are ordinarily used at opposite sides of the road for. confining the concrete or other road material, and to construct the carriage Vwith a drop Or underslung frame disposed between the temporary curbs so that the top surface of the turntable is not Objectionably high;

and to construct'the turntable and its car-.

riage so-that both will be entirely` out of Contact with ytheroad bed. Y

Another object is to construct and arrange tion of a portableturntable embodying the invention, showing the same associated with a concretemixingmachine and detachably connected thereto. Y

.suitable surface for lthe reception Of the concrete.Y Temporary metal or other curbs or forms are arranged parallel to each other at opposite sides of the road bed to confine the concrete until it vis vset and the forms are then removed. The concrete is Vpreferably discharged from the concretemixer, which is moved along the road bed in advance of the work. lt is not practical, however, to

drive the heavy loads of cement and sandV Vor other material for .the mixer directly to the mixer,`as trie space between the curbs is limited Vand turning the vehicle around would disturb the surface of the road bed. The material has, therefore, heretofore usually been discharged at some'distance from the mixer and then taken to the mixer in wheelbarrows or otherwise, which results in a considerable-expense for time and labor.

rihe present invention is intended to eliminate this expense and labor by arranging the turntable on a carriage adapted to travel along the curbing in such relation to the mixer that a truck Or vehicle can be driven over a relatively short, movable inclined approach up onto the turntable, and by rotating the turntable the rear end of the vehicle placed inpositioiito dump or discharge the material directly into the receiving hopper of the mixer.

The inclined approach, the turntable cai'- riage and the concrete mixer are preferably detachably connected together and may all be simultaneously moved along-as the work progresses.

In .F ig. l of the drawingsthe ioadbed is shown at l() and parallel metal curbs ll are arranged, as usual, at Opposite sides thereof and project above the surface of the roadbed. rPhe concrete is spread between these curbs as it isdischarged from the chute a of a concrete mixer A. These curbs may be of any .usual or suitable sort but are preferably of the form shown in the drawings1 each curb consisting of a metal rail .table C is preferably constructed as follows :V

The underframe- 24v before vmentioned, V

having a vertical wall 12 arranged on the inner side' ortoward the concrete iilling and forming a retaining wall therefor, a base flange 13 adapted to support the curb, and

an outwardly-bent, top iiange l4forming a or other vehicle B, and to be. raised fordischarging the-material into the mixing drum.

The mixingmachine A is mounted on .wheels to adaptv it to be moved along astlie work progresses. rlhe turntable C may be of any suitable construction adaptedto revolve on its supportingcarriage D.' The turntable C Vshown inthe drawings lcomprises, a central circular beariiigrfplate 20, rotatable on upper and lowerball bearings inA races 2l, 22V

providedy on a circular base 23, rigidly securedl on an underframe 24 of the carriage,

D, andaplatform25 secured on the plate 20, and,V comprising a frame composediof l beamsf26,l or lthe like, surrounded by a circularperipheral channel beam 27, Aand coveredwith planks 28 or the like to form the supportingisurface for vehicle B. Any other i suitable construction for thetuintable may be used.k e Y The supportingy carriageD for the turn- `preferably comprises spaced longitudinal beams35z connected between their ends by transverse bars 36, ,foriniiig'ay four-sided supportv for ahorizontalplateor the likel on whichthe turntable base 23 is secured. outer,v ends ,of the bars 35 are rigidly secured toparallehtransverse I; beams 3S disposed on opposite sides of the axis of the turntable C and their` length is substantially equalto the width of the road between the curbs l1, (see Fig. 3.) The opposite ends of these beams38 are suitably secured, as lby means of depending liangersor brackets 39, to carnear their outer ends on shafts 46.

riage side frames 40, 41, respectively, each of which preferably comprises longitudinal,

spaced, channel beams 42 extending parallel.

withandiat opposite sides of thetop-l4'rof the curbs 11, andconnected between their ends by spacing members 43. The hangers 39 areV conveniently secured between the'spac ing members 43 and the vertical; facev of one of thebeams 42. Y Y

Means are preferablyvp'rovided for bearing 'onthe'tops 14 of the curbs l1 for supporting the carriage thereon and permitting it to be `readily moved along onthese curbsas the work progresses. The means shown in the vdrawings comprise flanged rollers 45 ljournaled between the beams 42, preferably at or tionalrollers may be provided iii-necessary,

face of the turntable convenient height for driving the vehicles. thereon, and a strong, rigid construction' is` The naar i or any other suitable means for movably supporting the carriages D on the curbs ll could be used.

The carriage constructed as described with the underslung or drop Aframe extending low down between thevcurbs `enables the top sur- VA'to be located at a provided, and onewhich allows the turntable to be readily rotated and moved along the curbs.

An inclinedapproach 50 of any desired construction is providedwhereby a trucker vehicle may be driven from the road bedup onto the turntable. This approach is. port'- able andis readily moved withvtherturntable,

and is preferably detachablysecured,theretoy i as by hooked bars 5l bolted to the'longi-` tudinal frame bars ofthe approach and yproj ecting; therefrom and adaptedto behooked on the carriage under the frame, as showninf desired, the `turntable carriagefD may be detachably secured to the mixing vmachine A sothat these units as iwellas-thein'- clinedV approach 50 may. all. be simultane-V ously advanced .as the work progresses. For

this` purpose, adjustable connecting. rods 455 are shown which are attached atv oneendfto a part on the front endof the.mixing. ina- Y chine and atthe otherv ends are suitablysecured to the rear cross beam 38ofrthe carriage.' Any other.y suitable means mayv be, used for this purpose. Y

By the described-construction the support-r ing wheels for the turntable are locatedat the sides of the turntable beyondthe periphery' thereof andare adapted totravel on the usual raised curbsor tracks atfthey oppof.

close tothe roadbedisoithat the turntable can be located low downzwith the top only a short distance above the-roadbed, thus adapting trucksto be readily driven up onto and stoppedon the'turntable; Nevenrtheless,.the turntable,V and itscarriage are wholly supportedoii of the roadbed so as not tordisturb the same. The'turntable, its

inclined 1 approach and the 'mixing machineV are connected so that they can be moved orl advancedas a unit asthe work progresses, but they canbe readily'disconnectedlto facilitate the separate manipulation andtrans-V portation of the several devices'.y

I claim as my. invention:

In aroad construction apparatus, the combination of a turntable, a-carriage on'which said turntable isrotatablymounted, wheels site sides of'therroadibed; while the turn- Y Vtable carriage depends between the tracks journaledv onV saidY carriage ati-its opposite sides,andadaptedlto rollon raised tracks at opposite sides of the road bed-between which tracks said carriage depends, an inclined lapproach detachably connected to one endiof said carriage, and a machine detaohably connected to the opposite end of said turntable carriage, whereby a Vehicle can be driven up onto said turntable and turned to a position to discharge material therefrom into said machine, and said turntable, said approach and said machine can be simultaneously advanced as the Work progresses.
